Singing through your snout

Stick the forefinger of your right hand in a pig’s snout
Poke your left thumb in an antelope’s ear
You won’t be able to do the hokey pokey or sing a song of sixpence
What kind of creature will you become?
There you are rushing across the Savannah to your slop bucket
Is that you poking your shiny black horns into a mud hole?
I saw you stand on two legs.
I heard you sing about the blackbirds
You were singing through your snout
